SINOMER® HEMA-HP is an ultra-high purity grade of 2-Hydroxyethyl Methacrylate (HEMA) with a minimum assay of 99.6%. It is specifically designed for demanding applications requiring stringent purity standards, including soft contact lenses, ophthalmic devices, dental materials, and medical adhesives.
The product features extremely low impurity levels (EGDMA, DEGMA), low acid value, low moisture content, and a precisely controlled low MEHQ stabilizer level (10 ± 3 ppm) – a critical differentiator from industrial-grade HEMA. These characteristics ensure consistent polymerization behavior, excellent optical clarity, and superior biocompatibility in finished products.
